Public bug reported:
Hi guys,
apprently my box overheats under high load with more-than-moderate
environment temperatures, which triggers the kernel (correctly!) to
throttle the CPU. Apparently, this throttling (or some data transfer/DRM
issue?) causes the GPU to hang/lose communication (kernel bug? see
dmesg. MCE is just talking about temparature recovery), which causes
Xorg to misbehave.
Both displays go black (from top to bottom, one after another), and come
back again, and after that everything is horribly slow, Xorg uses
90something% of the CPU, and otherwise everything seems fine. Switchtig
to a VT is bearible and stops Xorg from using CPU, killing it makes
lightdm bring it up again and everything is seemingly fine. Same
behaviour repeats soon unless load conditions are relaxed.
So, this might be two bugs: one for the kernel to let the GPU hang /
don't handle this more smartly; one for Xorg to start consuming CPU like
crazy after this happened.
Please link this bug to the proper packages, and maybe link it to other
i915_hangcheck bugs, too.
Cheers,
count
